'7 Claims. (01. 30 94) This invention relates tonew and'usefulimprovements in a blade for safety razors.

This invention proposes the construction of a blade for a safety razoror other similar razor which is characterized by the fact that it hasmore cutting edges than the conventional safety razor blade withoutrequiring more material.

Still further the invention particularly proposes increasing the cuttingedges of a standard two edge blade so that it has four cutting edges,without an increase in-the material from which the blade is constructed.

Still further the invention contemplates an arrangement whereby aplurality of flat narrow blades with cutting edges at the sides arepositioned in the horizontal and associated with a means for holding theblades as a unit for engagement into a safety razor so that certain ofthe edges (the outer edges) of the blades are exposed for use, andwhereby the blades may be adjusted so that the other cutting edges arerepositioned to constitute the outer edges and then are exposed for use.

Still further the invention contemplates the arrangement of flat narrowblades with cutting edges at the sides and positioned parallel to eachother, and end elements cooperatively associated with the blades forholding the blades as a unit for engagement into a safety razor so thatthe outeredges are exposed for use, and wherein the blades may beadjusted so that the other cutting edges constitute the outeredgesexpo'se'd for use.

As another object of this invention it is proposed to associate endelements with theends of a plurality of flat narrow blades havingcutting edges at the sides in a manner so that the blades may beheldwith either of the cutting edges disposed outwards, and wherein'themem-' ber itself is adapted to be associated'witl'i the standard partsof a safety razor, that is, the cap plate and the guard plate for thepurpose of holding the blade as a unit within the safety razor ready foruse.

Furthermore as another object of this inven-- tion an arrangement isproposed whereby a memher is adapted for association in a safety razor,a plurality of flat narrow blades with cutting edges at the sides arearranged in the horizontal, 50 and cooperative means arranged upon themember and blades for holding these parts as a unit simulating aconventional blade for a safety razor.

The invention also proposes a provision wherer by" the flat narrowblades previously mentioned 5 are equipped with handles by which theymaybe readily adjusted from one to the other of their positions ofexposing either of their edges.

Still further the invention proposes the construction of articlesasmentioned which are simple'and durable and which may be manufac- 5tured and sold at a reasonable cost.

For further comprehension of the invention; and of the objectsandadvantages thereof, reference will be had to the following descriptionand accompanying drawing and to the appended 10 claims' in which thevarious novel features of the invention are more particularly set forth.

The blade for safety razors according to this invention comprises aplurality-of narrow-flat '5 blades 10 with cutting edges II at the sidesand positioned parallel to each other, in the horizontal and associatedwith a means for releasably holding said blades as a unit for engagementinto a safety razor so that the outer edges are exposed for use. Moreparticularly the means referred to according to the form of theinvention illustrated in Figs. 1-4 comprises end elements [2 havingdove-tailed projections.l3 adapted to ene gage in similar cutouts l4formed in the ends of the blades for holding the blades as a unit.

The cutouts M are extended through the thickness of the blades so thatthe end elements [2 may be assembled by just sliding the element intoposition so that the tongues l3 engage the openings Hi. When the bladeis engaged in the safety razor the cap plate and guard plate of thesafety razor will prevent the blades ID from becoming disconnected fromthe end elementsl2 in that these parts will be held against relative upand down motion.

The elements 12 are so constructed to facilitate the engagement of theblade within a conventional safety razor. For this reason, a fork shapedprojection I5 is arranged upon the inner sides of each of the elementsl2. These fork shaped projections l5 are adapted to engage theconventional central rib formed upon the cap plate of the safety razor.This rib is schematically illustrated by the dot and dash lines I6.

The dot and dash lines I! illustrate the cap plate 3 and 4.

of a razor. This cap plate is shown formed at the corners withprojections 18, as is a construction of a popular brand of razor bladessold on the market at the present time.

The end elements l2 are so arranged that they projections 18 engageagainst the endsv thereof and in this mamier the blade is safely and.securely held within the razor. In Fig; 1 the blades ID are shown havingtheir edges numbered I, 2, With this arrangementv records may be kept asto the number of times each of the edges are used so that the mostsatisfactory services can be obtained. from the blades. As illustratedthe blades H] are shownwith one of their edges disposed upon theoutside. These blades may be disengaged from the end elements and turnedaround through 180 and then reengaged in place so that the edges whichwerepreviously towards the inside are now disposed towards the outsideand ready for use when the blade is engaged into a safety razor.

In Fig. 3 a sectional view hasbeen illustrated.

in which the cap plate I! is shown coacting with the guard plate I9holding the blade according to this invention in place. From thisillustration it will be readily understood that only the outer edges ofthe blades ID are in position for use. A.

feature of this invention resides in the fact that without adding anyadditional material to that now generally used for the blades of asafety razor, two additional edges are obtained and thus the operativelife of the razor doubled.

In Fig. 5 a slight variation of the invention has,

been disclosed in which the blade is substantially identical to the formpreviously described except for the fact that end elements are usedwhich distinguish from the previous end elements in having largeprojections l5 upon the inner sides arranged so as to engage in adifferent type. of safety razor. The large projections 15. are formedwith several curved portions 20 and 2| arranged to produce openings forthe passage of. studs. This. razor blade is adapted for use in safetyrazors equippedwith studs. projecting from.

the cap plate through the guard plate as has been a very popular designin the past. There are large numbers of these razors still held by thepublic and with the arrangement disclosed in Fig. 5 the blade accordingto this invention may be used in that particular type of safety razor.

In Figs. 6 and 7 another variation of the invention has been disclosedinwhich the blade is equipped with a member 22 having several openings23 for receiving the various studs which are projected from the capplate through the guard plate of razors now on the market. This form ofthe invention distinguishes from the previous form in the arrangement oftransverse end portions 24 on the member 22 and of a greater thicknessthen the member 22, and arranged to adjustably hold the blades In. Moreparticularly the ends of each of the portions 24 are formed withprojections 25, constituting fork constructions for engagement upon bothsides of the blade I!) simultaneously. Located between the forkprojections 25 and upon the end portions 24 there are projections 26adapted to engage into niches 21 upon the blades I0 for the purpose ofholding the blades against displacement.

this arrangement it is possible to reverse the blades whenever desiredby merely flexing the blades to cause them to bend and allow. thedisengagement.

In Figs. 9 and 10 another variation of the invention has been disclosedwhich is very similar to the previous form except for the fact that thisblade is formed with a holder 22 having a longitudinal slot 28 inaddition to the openings 23 to adapt it to more than one type of safetyrazor now on the market. The member 22' is provided with end portions 24formed with openings 29 adapted to receive small tongues 30 projectingfrom the ends of the blades It]. With this arrangement it isnecessarythat the blades Ill be slightly flexed at the centers todisengage the tongues 30 from the openings 29 for the removal of theblades. With this arrangement it is possible to reverse the blades aspreviously described. The tongues 30 are of flat construction engagingin the round openings 29, so that the blades are firmly held fromfalling out but may be rotated without removing the blades from the endportions 24.

In Figs. 11-13 inclusive, another modified arrangement of the bladeaccording to this invention has been disclosed which distinguishes fromthe previous type in the provision of a member 22 having cutouts at theends producing a. fork construction 32. The inner faces of this forkconstruction are formed with small longitudinal recesses 33 forreceiving a shank in'a manner so that the shank may snap into place.With this arrangement the blade [0 is provided, which has tongues 34projecting from the ends. These tongues are permanently engaged withstuds or socket elements or shanks 35 adapted to engage the fork 32 andsnap into the recesses 33. The studs 35 are formed with heads 36 adaptedto normally be disposed outside of the portions 24 in a manner so thatthe blades'lll may be reversedwithout their removal from theholding'member, by merely gripping the heads 36 and turning the heads tocause turning of the blades.

In Fig. 14.an assembly of the cap plate Hand the guard plate I 9 hasbeen disclosed inconjunction with, a blade. according. to. this;invention.

With this arrangement the blades [0 must be snapped into and out ofposition. With The blade is shown to comprise the blade portions inwhich are disposed in between the cap plate I! and I9 and which havetheir ends slightly projecting and the enlarged end portions 24previously described. The purpose of this view is to illustrate themanner in which the end portions 24 are located outside of the area ofcap plate and guard plate so that the construction and assembly of thedevice may be readily understood.

It is to be understood that the blade holders may be made of anysuitable material, such as metal, composition, etc. and that the bladesmay be either sold with the said blade holders or separately for fillingthe blade holders.
